MILAN — Diesel chief Renzo Rosso confirmed this morning he has taken a majority stake in Marni through his holding company Only the Brave Srl, during a press conference here with Marni’s founders Gianni and his wife Consuelo Castiglioni.

Rosso and Castiglioni, who held the chief executive position at Marni, will become co-ceos, and creative director Consuelo will remain head of design.

“It’s a wonderful, global company and an iconic, fantastic, creative and recognizable brand,” said the ebullient Rosso. “We will provide new energies and resources to add brilliance to the label.”

Castiglioni said he and his wife were looking for a “long-term, or “no-term” partner” with know-how that would share their vision and help fully develop Marni.

“The partnership evolved naturally, stemming from two families that are friends,” said Castiglioni. “Marni’s identity will not change, but we will be able to compete in a complex market with brands that are part of major fashion groups.”
